SPECIFICATION forming' part of Letters Patent N0. 476,051, dated May 31, 1892.

Application tiled October 3, 1887. Renewed December 3, 1888. Serial No. 292,536. (No model.)

To all whom t may concern:

Be it known that I, CHARLES H. LIEDKE, a citizen of the United States, residing at Sandusky, county of Erie, and State of Ohio,

have invented certain new and useful Improvements in Crayondl/Iachines; and I do hereby declare the following to be a description of the same and of the manner of constructing and using the invention in such full, clear, eon

to cise, and exact terms as to enable any person skilled in the art to which it appertains to construct and use the same, reference being had to the accompanying drawings, forming a part of the specific-ation, the principle ot' the i5 invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to crayonmachines zo It has for its object an improved form of mold-plates and mold-plate frames, the moldplates being pivoted or axially journaled that they may be partially rotated and the crayons loosened or forced from the moldz 5 plates.

Figure l is a reverse plan view of the moldplate frame with the mold-plates in closed position. Fig. 2 is a side elevation of the same parts in closed position. Fig. 3 is a side ele- 3o vation View of the mold-plate frame, moldplates, and connecting parts, the actuating mechanism being shown in its first position of movement. Fig. 4 is a side elevation view of the mold-plates and the actuating mech- 5 anism, the follower, links, and lever-bar, the latter being shown in their second position of movement. Fig. 5 is a detail view, partly in lelevation and partly in section, of the first half 1noldplate, the spring-bearing plate, and

4o manner of connecting the mold-plate wit-h the links, the View being taken on the dotted line of Fig. 1l. Fig. 6 is a detail view of lever, the dottedlines showing lever in folded position. Fig. 7 is a detail elevation View of the link. Fig. 8 is a detail view, partly in elevation and partly in section, of the follower and connecting parts, taken on the left-hand dott-ed line of Fig. l and in the direction of the arrow. Fig. 9 is a detail view, partly in section and 5o partly in elevation, otthe rock-shaft and connecting parts, taken on the right-hand dotted line of Fig. 4. and in the direction of the lefthand arrow. Fig. 10 is a plan view of moldplate frame and mold-plates, the actuating parts being omitted. Fig. 1l is a vertical cen- 55 tral longitudinal section of the incid-plates, follower, links, and lever, the mold-plates being in open or angular position.

A is the mold-plate frame, provided ateither end with the journals c, by which they may 6o be journaled in arms of a crayon-machine similar to that described in application Serial No. 148,635, of J. S. Cowdery, tiled November 23, 1884.. Each of the side pieces A" of the frame A is provided with a longitudinal rabbet d', having shoulder a2, and with a slot a3 opening transversely through said side pieces.

A follower Bis journaled at either extremity in the two-part journal-bearings C C', the lower part C of which fits in and has sliding 7o bearing in rabbet a and is provided with shoulder c, which engages with shoulder a2 of said rabbet, the upper portion C resting on said extremities or journals t) and having sliding bearing on their upper side against retainingstrips C2, secured to the side pieces A. Threaded into the central upper portion of said follower and rising therefrom is the rod D. Cross-bar d lits on the upper part of said rod andisadjustably secured thereto by means of set-screw d2. A series of half moldplates E, each of which is provided at either end with journals e, is also journaledl in the two-part journal-bearings C C', the first half mold-plate of the series being provided on its forward plain surface with the bearing-plate e', against which bears the spiral springez, said spring in turn fitting and having bearing in the opening e3 in the mold-plate frame. The last half mold-plate of the series is provided on 9o its rearsurfaoe with the triangular lug `which engages with rod D at certain portions of its movement. Cam-lever F is pivoted by boltf to the lugsf, secu red to the forward portion of the mold-plate frame, the lower cam portion F of said lever being provided with a series of holes f2, by means of which the throw of the cam may be varied. A slot g is also formed in said lever, while the upper handle portion F2 is provided with a pivotal joint g', Ioo

' sleeve g2, located thereon, the interior of said sleeve being provided with spring 71.4 to hold the sleeve in place. Passing transversely through said slot and secured thereto by nuts g4 is bolt g2.

opposite ends of which are secured to crossbar d by screws h. The links at their forward ends are provided with a series ofholes h', through one of which the bolt g3 passes, and by means thereof the throw of the links may be adjusted.

Rock-shaftJ is journaled in the sides Aofy the mold-plate frame, its extremities .7' j pro-.

jeeting on either side of the same. Keyed on either ot said extremities are the cams K K,

provided with pins k, on which are pivoted` connecting-rods L, having their opposite ends` pivoted on bolts 7c', which are screwed into shaft B.

of connecting-rods M and also in slots a3, said rods being secured at their opposite ends to theffirst half mold-plate abutting the rockshaft by bolts m,'which have sliding bearing in longitudinal slots m2, formed in the sides l A ofthe mold-plate frame. Cam K is provided withlever-handle K2 and also with stoppin 102, whicli,engaging with bolt k2, limits the tively discharged and forced from their molds;

movement of said lever-handle. p

The operation of the machine is as follows:

Letit be understood'that the mold-plates andv actuating mechanism are vin the positionf shown in Figs. land 2, the lever-handle K2 beingparallel with and resting upon the connecting-rods L. It may also be understood that themold-plates are tilled with crayons.

The lever-handle K2 is raised to a verticalposition and again depressed until it is again parallel with but removed from the connect-`v ing-rods L and vstop-pin k2 is in engagement This position is shownv in.

with the vbolt 7c3. Fig. By this movement the connectingrodsL are thrown backward, carrying in their movement the follower B, to which they are secured by means of the bolts 7c. Said bolts also pass through and have sliding bearing in the slots m ofl the connecting-bars M, and

hence'as said bolts are moved backward the' connecting-bars M are caused also to move backward and draw with them the lirst half v mold-plate of the series adjacent to the rock- Vshaft J. The mold-plates all heilig in close contact, the movement of said tirstmold-plate causes the entire series to be correspondingly moved. The operator then grasps the lever-handle F2, which is now in the position shown in Fig. 3, and moves it backward toward the follower, causing the cam portion F to engagel with and tilt backward the said iirsthalf mold-plate, which causes a correspending tilting of all the mold-plates ot the series. The said mold-plates are pivoted eccentrically relative to one another, and this tilting or partial rotating causes the upper and lower faces of the mold-plates to be lo- To this is secured on either side of said handle by said nuts the links H, the

Said bolts also pass through and have sliding bearing in longitudinal slots mj cated angularly to one another, as shown in Fig. 4. The crayons are thus loosened from one half of the mold-plate walls. Lever-handle F2 is then moved in a reverse direction to that just described, causing rod D to engage with the lug d, located on the last mold-plate of the series, causing the mold-plate to be partially rotated in the opposite direction, and thus force the crayons in positive movement from the mold-plates, as will appear from Fig. l1. Again the lever-handle F2 is moved until it assumes a position practically vertical and by its engagement with the rst half moldplate causes the :mold-plates to assume a vertical position, the spring e2 exerting a pressure on said mold-plate below the point of journaling. The lever may now be reversed into the position shown in Figs. 1 and 2,'the regulating movement of the follower causing the mold-plates again to be brought into close contact in 'a vertical position. ment of the mold-plate causes thecrayon to be loosened or freed forcibly from one half of the mold as the half-mold in each mold-plate is depressed below the corresponding andadjacent half-mold inits abutting mold-plate. The reverse movement of `the mold-plates causes a corresponding reversal and depression of the opposite side of each mold-plate, and by this movement the crayons areposibut as the force exerted is applied inthe direction of the crayons length there isno probability of the crayons being broken.
